Refrigerating Cake Covered In Mmf???

I am making a two tiered cake for a baby shower tomorrow. I am going to cover it with marshmallow fondant. I am debating whether or not to cover the cake tonight and put it in the refrigerator or should I cover it tomorrow before the shower???

How do marshmallow fondant covered cakes do in the refrigertator over night???

The rule is to take them out 2 to 4 hours prior to their destination so the condensation can dry. If for some reason it has not dried, a quick once-over with a hairdryer will do the trick (only after it's been out at least 2 hrs).
